摘　　要：针对南疆民丰戈壁沙漠地区 ,应用遥感技术 ,在地貌、水系、构造、古河道等系列解译的基础上 ,根据不同植被的影象特征建立了找水模型 :以鲜艳大红色彩者 ,划分为喜淡水湿生型植物群落 ,表明以叶绿素含量极高阔叶植被为主 ,主要分布在河床、河漫滩与古河道地带 ,属淡水 ,水位埋藏较浅 ,且丰富稳定 ;以褐红色、紫红色影象特征者 ,划分为喜咸水湿生型植物群落 ,表明为耐盐碱性极强的叶子很小、叶杆多刺植被 ,主要分布在沼泽或盆地 ,属咸水 ;以红色星点状影象特征者 ,划分为耐旱的旱生型植物群落 ,表明植被呈丛状零星分布 ,根系非常发达 ,主要分布在固定与半固定沙丘 ,水位埋藏较深。进而解译确定了地下水溢出带、补给区及其水质由南向北 ,潜水矿化度由 <1 g/ L增高至 5～ 7g/ L的水质变化特征。最后于沙漠盆地边缘的民丰、玉塘一带寻找出具勘探前景地下水供水源地。The model for locating underground water has been set up applying remote sensing technique,on the basis of interpreting reflections of landscape,hydrographichal,ancient river course in the desert area in Minfeng District,Xinjiang Autonomous Region.The bright red color reflection is interpreted as vegetation community fond of fresh water and dump soil that stands for broadleaf vegetation rich in chlorophyll.They are distributed in riverbed,flood land and ancient river course area which is abundant in fresh water.The brown red and purple red reflection is interpreted as vegetation fond of salt water damp soil that stands for salt resistant little leaf and thorn vegetation community.This vegetation community is distributed in salt water areas,such as salt swamp and salt basins.The red tiny spot reflection is interpreted as drought resistant vegetation community that stands for jungle vegetation.They are distributed in stable and unstable sand hills.Whose water level is very deep.Then the overflowing area and charging area is decided.The mineral density of underground water increases from less than 1 g/L to 5～7 g/L from the south to the north.At last the underground water source fit for exploring is found in the desert fringe of Mingfeng and Yutang District.
